Datasets and Supporting Materials for the IPIN 2022 Competition Track 3 (Smartphone-based, off-site)

This package contains the datasets and supplementary materials used in the IPIN 2022 Competition. Contents: Track-3_TA-2022.pdf: Technical annex describing the competition (Version 2) 01 Logfiles: This folder contains a subfolder with the 89 training trials a subfolder with the 24 testing trials (validation), and a subfolder with the 3 blind scoring trials (test) as provided to competitors. 02 Supplementary_Materials: This folder contains the matlab/octave parser, the raster maps, the files for the matlab tools and the trajectory visualization. 03 Evaluation: This folder contains the scripts used to calculate the competition metric, the 75th percentile on the 31|61|61 evaluation points. It requires the Matlab Mapping Toolbox. The ground truth is also provided as 3 csv files. Since the results must be provided with a 2Hz freq. starting from apptimestamp 0, the GT files include the closest timestamp matching the timing provided by competitors for the 3 evaluation logfiles. It contains samples of reported estimations and the corresponding results. Please, cite the following works when using the datasets included in this package: Torres-Sospedra, J.; et al.

本套件包含IPIN 2022国际定位与室内导航竞赛（IPIN 2022 Competition）所使用的数据集与辅助材料，具体内容如下：
1. Track-3_TA-2022.pdf：竞赛技术附件（第二版）
2. 01 Logfiles：该文件夹包含三个子文件夹，分别存储供参赛选手使用的89组训练试验数据、24组测试试验（验证集）数据，以及3组盲测评分试验数据。
3. 02 Supplementary_Materials：该文件夹包含Matlab/Octave解析器、栅格地图、Matlab工具相关文件与轨迹可视化文件。
4. 03 Evaluation：该文件夹包含用于计算竞赛评估指标的脚本，该指标为31|61|61评估点上的75百分位数。本工具需依赖Matlab地图工具箱（Matlab Mapping Toolbox）。真值数据以3个CSV文件的形式提供。由于参赛结果需以2Hz频率提交，且起始时间需从apptimestamp 0开始，因此真值文件包含了与3个评估日志文件中参赛选手提供的时间戳最匹配的采样点。该文件夹还包含了提交的估计结果示例及对应评估结果。
